Because of the likelihood of running into an exception, we need to make sure we wrap the updates inside a structured exceptionhandling block. Once an exception is thrown, several options to resolve the exception exist. The DataContext helps discover not only the object(s) that are in conflict, but also which properties are different between the original value, the changed value, and the current value in the database. In order to provide this level of information, we can specify the RefreshMode to determine whether the conflicting record is first refreshed from the database to determine the current values. Once we have the refreshed values, we can determine whether we want to retain the original values, the current database values, or our new values. If we want to take the last option and make sure our values are the ones that are retained, we resolve the change conflicts of the context object specifying that we want to keep the changes. Listing 8.4 illustrates a typical try-catch block to make sure our changes are retained. c# convert docx to pdf: How to convert a word file( docx) to pdf using asp.net c# - C# Corner c# pdf editor C# ASP.NET PDF Editor Control: create, view, annotate, redact, edit ...

And i wanted to add PdfPTable through code to add ... try { context.SubmitChanges(ConflictMode.ContinueOnConflict); } catch (ChangeConflictException) { context.ChangeConflicts.ResolveAll(RefreshMode.KeepChanges); context.SubmitChanges(); } If we use the KeepChanges option, we don t need to inspect the changed values. We assert that our values are correct and go ahead and force them into the appropriate row. This last-in-wins method can be potentially dangerous. Columns that we didn t update will be refreshed from the current value in the database. If the business needs demand it, we could merge the changes with the new values from the database; simply change RefreshMode to KeepCurrentValues. This way, we ll incorporate the other user s changes into our record and add our changes. However, if both users changed the same column, the new value will overwrite the value that the first user updated. To be safe, we can overwrite the values that the second user tried to change with the current values from the database. In that case, use RefreshMode.OverwriteCurrentValues.

The C# and VB.NET PDF Library. C Sharp ASP .NET PDF Generator / Writer. A DLL in C# asp.net to generate and Edit PDF documents in .Net framework and . The standard query operators provided by the LINQ framework allow queries to be a first-class language construct in C# and VB.NET. As we learned earlier in this book, the standard query operators operate over a sequence, where the sequence is an object whose type implements the IEnumerable<T> or IQueryable<T> interface. In the case of LINQ to XML, the some type T is typically an XElement, XAttribute, or XNode. In order to use the standard query operators with our XML data, we need to be able to search our XML for a sequence of objects that can then be queried using the standard query operators. The LINQ to XML axis methods provide a means by which we can find the elements, attributes, and nodes that we want to work with within our XML. Throughout this section we re going to introduce you to the various axis methods and explain when to use each. Once we have a firm handle on the axis methods, we ll look at how we can use them along with the standard query operators. To get started, let s look at the sample XML file that we ll use throughout this section for learning about the axis methods. The XML in listing 10.1 represents a subset of the books within our LINQ Books catalog. private void EndCalculate( IAsyncResult ar ) { CalculationDelegate del = (CalculationDelegate)ar.AsyncState; string result = del.EndInvoke( ar ); lock( this ) { _calcState = CalculationStatus.NotCalculating; FireStatusChangedEvent( _calcState ); } } Type that all as a single command. You only have to do this once in a given shell session, but it doesn t hurt to run the command a second time. This command loads a portion of the .NET Framework, Microsoft.VisualBasic, that PowerShell doesn t automatically load. This portion of the framework contains most of the Visual Basic centric framework elements, including things like graphical input boxes.
